If you make espresso at home, a coffee knock box is one of the simplest ways to upgrade your routine. It lets you empty your used coffee grounds fast without walking over to the bin or messing up the sink. Just tap your portafilter on the knock bar and you're ready for your next shot.
Also known as a coffee dump bin or coffee knock bin, this compact container helps keep your coffee station clean and easy to maintain. Whether you're pulling one espresso or making a round of flat whites, it adds convenience without taking up too much space.
If you're still rinsing grounds into the sink, it's time to stop. Coffee grounds don't dissolve and can quickly clog your pipes. A knock box gives you a better, cleaner way to deal with them. It protects your plumbing, keeps mess under control and makes cleaning up after brewing faster and easier. Do your bit to support the environment by using the coffee grounds for composting or garden soil. Investing in a good knock bin is a smart move for any home barista.
Start by thinking about how many coffees you make each day and where you plan to keep the box. Smaller models are ideal for tight benches, while larger options are great if you brew more often.
Look for:
A knock box is a key part of setting up a more efficient and enjoyable coffee space at home.
Used coffee grounds contain moisture. If they sit in the knock box for too long, they can start to grow mould or create unpleasant smells. Empty and rinse the box daily, or at least every second day, to keep your coffee area clean and hygienic.
Many people keep their knock box alongside other essentials like mug trees, coffee canisters, or a paper towel holder to create a complete coffee zone.
You can find more practical solutions in our bench storage collection or browse kitchen organisation for easy upgrades to your everyday routine.
It's used to collect spent coffee grounds after brewing. Just knock the portafilter on the bar and the grounds drop into the box.
Empty the contents into the bin or compost, then rinse with warm soapy water.
Absolutely. Coffee grounds are great for composting or for garden soil. Just make sure to empty the knock box regularly.
Smaller models are great for one to two coffees a day. Larger ones are better if you brew often or want to reduce how often you empty it.
